Do a quick conversion: 1 moles Beryllium Hydroxide = 43.026862 gram using the molecular weight calculator and the molar mass of Be(OH)2.
Homework Statement (Q.) 3 g of activated charcoal was added to 50 mL of acetic acid solution (0.06N) in a flask. After an hour it was filtered and the strength of the filtrate was found to be 0.042 N. The amount of acetic acid adsorbed (per gram of charcoal) is :Homework Equations...
You need to multiply the molar mass of the substance by the number of moles: As you can see, the most difficult task here isfinding out the molar mass of the substance. The molar mass of the substance Themolar massis a physical property defined as the mass of a given substance (chemical...

016 AMU. A mol of hydrogen gas has a mass of 2.016 grams. In that 2.016 gram mass is Avogadro’s number of H2 molecules because that is the way hydrogen comes. A mol of water is 18.016 grams because each water molecule has two hydrogen atoms and one oxygen atom. A mol of water ...
moles of water = molecules of water / Avogadro's number moles of water = 3.35 x 1022/ 6.02 x 1023 moles of water = 0.556 x 10-1or 0.056 moles in 1 gram of water
Systems of moles • Similarly, 5 kg-moles = (5 kg-moles)*(2.20 lb-moles/kg-mole) = 11.0 kg-moles Since there are 2.20 lbs per kg Converting between mass and moles • Mass = (Moles) x (Molecular Weight) • Therefore,
